Stretched lens array: The answer to improving solar array reliability

Solar array anomalies are a serious issue affecting the satellite industry and are responsible for increased insurance premiums and a negative perception. It is well known that the reliability of solar arrays needs to be improved. This can be accomplished through the use of a solar array that is inherently designed to withstand the most common modes of failures. The stretched lens array (SLA) overcomes traditional solar array anomalies and is reliable and affordable. This paper will focus on orbital array failures and approaches to design against such anomalies. Theoretical modeling and SLA ground testing results will be presented to prove the SLA´s resistance to arcing, micrometeoroid impact, and radiation exposure along with its ability to support high voltage operation. The SLA can overcome solar array anomalies and improve the reliability and cost affordability of solar arrays.
